Hi p3rty8,
"Amp Grd" protect in other brand is an error code for short and overload. Once the power applied to the unit and shorts sensed by the processor the unit will automatically turned to "Amp Grd" to avoid further damaged to other parts. Most shorts is in the supply voltage (B+, Vcc) line and most common caused is the sound output IC (mounted in heat sink). This part is responsible for amplifying the audio from the pre-amplifier stage and will feed to your speakers.
If you have a knowledge in disoldering and soldering technique, I would advice you to pull-out this part and then try the unit. If the "Amp Grd" error code is gone then you must replaced this IC with a new one to back your unit in normal operation again.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Want to know what the colors are for the stereo wires

At this stage of the game(25 yr old car) make your own. Run 2 wires from battery (B+ and GRD) to radio. Make sure you put a fuse in the B+ circuit according to Radio's spec's. Install antenna wire in radio and if you don't know what color speaker wires are remove a speaker look at its wiring and locate them under the dashboard. If can't locate them buy some and install them. You need a B+ and Grd wire for each speaker from speaker to radio.

Have a pioneer car radio model deh-p3100ub has power and good grd. it will not turn on is there a reset. fuse is good

do you have power going to both the red and yellow wires??? yellow is constant power (to retain memory) and red is switched (ignition). both wires need to see power before the unit will turn on.

My clarion cd player in my boat was working fine now it says amp grd. I have looked but i see nothing unhooked what can i do to get sound out of my speakers?

Remove all the speaker wires.

Power the radio back on and verify it is not the radio at fault.

If it powers up, check the speakers with a Digital Multimeter set to OHMS 20x.

Each speaker should have a resistance of 4 ohms. (or 8 in some cases)

Any variance (+/- .5ohms) means the voicecoil is blown, and replace that speaker.

I got a stock ford JBL amp with no wiring diagram i need to know what wires are what i have tryed to test for the power wirer but no luck.

ok on most amps there are two sets of wire ports one for speakers & one for +12v,grd & 12v remote start if you look over each port it will say what port is for what wire if it is in a connector it gets slightly more complecated what you do is with a vm check from wire to chassis ground [like seat bolts] 12v with key off when you cet power isolate wire then turn key on till radio comes on then do the same test for 12v isolate that will be remote start then turn key off &check from the first wire to other wire for ground to find speaker wires connect a regular peace of wire to chassis grd & touch the wires you will here the speaker pop be sure not to hold the wire on long cause it will blow the speaker

No power turn on??

Does the voltage at the battery drop when you connect 12v to the remote terminal?

If not, there is too much resistance in the power/ground wiring.

If the voltage drops at the battery, either the battery is weak or the amp is drawing excessive current.
